Abstract: ABSTRACT            A natural gas, which in addition to methane contains 2 to 4 carbon atoms per molecule and H2S, is treated to remove the H2S and the hydrocarbons in part. The natural gas under a pressure of at least 5 bars is indirectly cooled in a heat exchange zone to temperatures from -30 to -100°C.          The condensate is removed from the cooled natural gas and is pressure-relieved and is then passed as a coolant through the heat exchange zone. Scrubbing liquor is cooled in the heat exchange zone to temperatures from -30 to -80°C and is con-tacted in a scrubbing zone with the natural gas from which the condensate has been removed. The laden scrubbing liquor which has been withdrawn from the scrubbing zone is passed through the heat exchange zone. The natural gas which has been purified in the scrubbing zone is pressure-relieved and is also passed through the heat exchange zone.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention concerns an air blower including a centrifugal fan which is driven by an electric motor.  The blower has a two-part blower housing comprising an upper housing which encloses the motor beneath the motor cap and a lower housing.  The centrifugal fan is disposed in the chamber between the upper end lower housings.  The plenum around the fan leads to an outlet from the blower.  An intake shield extends across and blocks undesired entrance of objects into the inlet opening in the bottom of the lower housing.  The blower may be seated on a lid across an opening in it.  An adapter in the lid receives the intake shield and has its own air inlet to the blower. The orientation of the blower with respect to the lid is rotatable.  Cooperating flanges on the blower and the adapter hold the blower to the lid at two rotative locations and a button latch arrangement latches the blower at each of the two arrangements.  Between the two latched orientations, the blower may be lifted free of the lid.
